The object of myinvention is to provide a new and improved chip-breakerfor woodworking-machines, whereby the pressure may be selectivelydirected to difierent points transversely of the cutter-head; and itconsists in providing a pressure device for the chip-breaker arranged tobe adjusted to different positions longitudinally of the cutter-V head,and, further, in the parts and in the construction, arrangement, andcombinations of parts hereinafter more fully described and claimed.

In the drawings, Figure 1 is an end elevation of myimproved deviceshowninconnection with adjacent parts of a woodworkingmachine. Fig. 2 isa plan view of the same. Fig. 3 is an end elevation of my improveddevice partly in section for better illustration of parts. Fig. 4 is aside elevation of my improved device shown in raised position, and Fig.5 is a detail in end elevation of the swinging arm for the same.

A represents the frame of the machine, in

which a cutter-head. B may be suitably journaled, and 0 represents achip-breaker.

1 is a swinging frame having abearing 2, taking about a rod 3, securedin lugs 4 to'the frame of the machine. The frame 1 has a 4'0 planed face5 for receiving a similar planed end of a chip-breaker support 6, bolts7 taking into the support through slots 8 in the swinging frame 1, andthereby affording ad- .justment of the same toward and away from thecutter-head. At its lower end the supportcarries a chip-breaker bar orfoot 11, ad- .jnstable thereon to and from the cutter-head by means ofhaving bolts 12 take through slots 15 in the support and screwing intothe chipbreaker. The support carries a rod 15, upon quire.

which a pressure-lever 16 is adapted to swing. The pressure-lever isalso adjustable sidewise with relation to the chip-breaker bar, as bybeing slid 011 the rod, so as to exert the pressure, as from a weight17, against any desirable point transversely of the chip-breaker. Thepressure-lever preferably has a downward extension 18 and a rearwardextension 19. A bolt 21 screws through the lever and is held firmly inplace by means of a'set-nut 6o 22. A spring 23 preferably takes aboutthe bolt between the lever and'the support with the end of the bolt 21normally held out of contact with the support by the spring, the springthereby serving as a cushion between the pressure-bar or chip-breakerand the weight. A bolt 25, adjustable in the swing ing frame, limits thedownward movement of the chip-breaker by having the end of the 5 bolttake against the frame of the machine.

My improved construction permits the chipbreaker to be swung upwardlyand slid transversely out of the way, one or both movements beingresorted to, as occasion may re- It also permits ready adjustment of thechip-breaker with relation to the cutter head and, further, permits thepressure to be exerted at the point where greatest resistance is desiredtransversely of the machine by permitting the sidewise movement of thepressure agency.

' I claim- 1. In a woodworking-machine, the combination with acutter-head, of a chip-breaker therefor, and a pressure device for thechipbreaker, with means for permitting the sidewise movement of thepressure device transversely of the chip-breaker, substantially asdescribed.

2. In a woodworking-machine, the combi- 9o nation of a chip-breaker,means for permitting the same to swing, a lever for the chip breaker, aweight for the lever, a spring interposed between the lever and ,thechipbreaker, and means for permitting the sidewise movement of the leverwith relation to the chip-breaker, substantially as described.

3. In a woodworking-machine, the combination of a chip-breaker, aswinging frame therefor, a rod for supporting the swinging 10o frame,means for permitting sliding sidewise In testimony whereof I have signedmy of the swinging frame upon the rod, aweightname hereto in thepresence of two subserib- IO ing device for the chip-breaker, with meansing witnesses.
